OK- The light's finally going on here- the hose that goes onto this nipple, it's got vacuum, question is where does it go?

 

That's been posted over and over in this thread

 

The nipple goes into the valley of the engine but the hose that attaches to it...……….

 

It goes to the intake. Spray the **** in that hose. It has vacuum because it's hooked to the intake. Spray it there.

 

ok- all done but I elected to spray in thru the throttle body as idle was unaffected at the pot. Also learned ya can't nudge open the throttle body for a hose then try to start the truck; got every fit and idiot light on and a couple emails from OnStar telling the truck is freacking out I almost shat a brick...………..

 

lol, OnStar yelling at you...

So, after all this, does it run any different?

 

Yes- a little crisper and smoother...………...

 

That's why you don't do it that way. Tried to tell you how to.

I only do it through the throttle body if I can use the S tool I told you about, and posted pictures and links to. You can't get the spray through the throttle body properly with that can spray and the intake tube needs to be connected or the MAF wont read and it'll have all kinds of issues.

I can only try so hard to help and for the life of me I can't figure out why you ask how to do it over and over and still ignore the advice. I've done all this hundreds of times.

If you would have used it in the hose I told you to spray it in it would have done a more thorough job and you would have less problems.

Ever heard of an ASKhole?

 

Yeah, well- Merry Christmas to you, too...…………..

 

Do you still want to get ahold of Sam to have him tune your truck?
